neo4j-shell 连接在 aws 上被拒绝

我已经在链接中查看了有关同一问题的另一个问题

Linux 端口在本地开放，但在外部不开放

neo4j-shell -主机 127.0.0.1 -端口 1337

我得到了错误

telnet 127.0.0.1 1337 工作正常 telnet 10.142.85.146 1337 失败

我发现这里有一些相似之处；neo4j-shell 正在寻找 10.142.85.146，但找不到它

我能够正常使用公共 IP 地址；但本地地址存在问题

任何帮助都将不胜感激。我不想再提出另一个问题，因此在同一个帖子中写道

附加信息最奇怪的是，我的 AWS 控制台显示私有地址是 10.142.65.14，如何将其转换为 10.142.85.146，我不知道

答案1

我根据 AWS 命名约定用当前 IP 和主机名更新了 /etc/hosts，一切开始正常工作。

我正在查看这篇文章以便在每次启动时自动更新它们 http://www.onepwr.org/2012/04/26/chef-recipe-to-setup-up-a-new-nodes-fqdn-hostname-etc-properly/
